Isolated Subscapular Muscle Rupture

A 70-year old female presented at the Orthopaedic Polyclinic with complaints of pain in the left shoulder which increased particularly at night. There was no history of trauma, surgery or injection in the shoulder region. Physical examination revealed no soft tissue swelling and ecchymosis. Anterior aspect of the glenohumeral joint was painful. Internal rotation was limited. Active abduction could be performed to 50 degrees. On MRI, on the axial fat-sat T2 series, the subscapular muscle tendon was ruptured. The biceps muscle long head of the bicipital groove was displaced towards the medial. Shoulder-sling was applied to upper extremity and nonsteroidal antiinflammatory analgesic treatment was initiated. Subsequently, physical therapy was planned for the joint maintance (Figure 1&2).
